while the upturned hook (3 at the end of the transverse Il'lOiJ'llXPlfurnishes a sii'igle seat. I for hearing on the. edge of the oppositehase flang l hese three seats constitute the three points for etleot-ivehearing hetweon the anticiieeper and the rail and will he do scrihed ingreater detail hereinafter.

The seats 7 and 9 in C()11'll)lI12ll.l()I1 with the adjacent portions ofthe transi'e 2 i'ncniher are shoulder seats only and constitute thefulcrui'n or hearingpoints for a lever grip on the ail hase operating in1 i a horizontal plane. while war 7 with the adjoining portion of thetransverse bar and seat 8 with iis upper portion n'iarked 8, where thepart "i is bent. down over tho-rail hase (.(l iflt. constitute thefulcrum or hearing points to a lever grip on one base flange operatii'igin a vertical plane. The lever grips are dereloped in functionaloperation as hcreinalter d cs0 ri lied.

Tho tie-abutting part 4- is oil'set: partly under the edge of theraihin-oviding a short liiearing 8 on the underside of the rail. at seat8. The three surfaces of contact 8, 8 and i constitute a shallow jawscat which for the purposes to he served is made as close fitting and asrigid and unyielding in l'ori'n as possible. This jaw seat. has atwo-fold Inirpose as will he disclosed in the description of theinstallation and functional operations.

As indicated in Fig. 4-. the nuinufaclurcd shape of the device is sin-hthat. if ii ho assumed that the seats 7 and 1) are in position the jawseat; (.IKZJIOLHJlNZS in war-Ally and upwardly on the spacerequired h)"the rail hase on which it is to he seated.

A featureespecially to he. noted here. and mu of those distinguishing my presenlorm oi' device from that. of my prior patents. is thai; the two strainsal'iorc des rihed are added in H1?- tion and do notmalerially diminishthe resultant ell'eet. To illustrate:----'lhe rotation in a transverse.vertical plain: f the jaw downwardly. or clockwise as viewed in Fig. l,producing a torsional strain in the l ngitudinal i'i'ien'ilier only,would hring the jaw seat, h inwardly and reriluce ihe spare i twee-n itand seat 5). As a consetuieinto a greater strain iii-proportion to thatreduction must. he developed in part 5 when jaw a fulcrum.

:5. This development of strain hereinafter further descrihed in settingforth the manner of installing the anchor.

it is to he noted that the internal strains developed as descrihed inthe last; paragraph provide a constant initial grip on the rail that isoi' importance in the maintenance of a genuine lever grip duringfunctional open ation. These internal strains will not be increased orn'iaterially diminished by the normal tie reaction indicated hy thearrow 10 in Fig. l.

The jaw seat I; with its hottoin part8"; in addition to holdin; theinternal strains developed by installation. has the. further purpose ofholding' the free end of the transverse mcniher Ming against the base ofthe rail. This pur 'iose isaccomplished directly hy the torsional strainin the upper portion oi" menihor 2. The upturned hook (3 has a lip (3slightlyoverhanging the rail base edge. This overhanging portion is notessential, however. in holding the device in operative position as in myfirst prior patent cited.

At installal ion the device is l'irst placed on the rail hy hand alittle distance away from the tie in the position illustrated in Fig. 5,with the portion 3 ol the longitudinal incinl'icr re ting on the railhase and with the tr: nsi'erse nicmher extending under the rail as faras it will go freely with the hook (i lackingnearly its tall thicknessof coming into the clear. hammer blow is next ap plied in the directionindicated by the arrow .11 in lrig. to bring the device to the, positionof Fig (3.iotating the jaw seat downwardly into place ahouli the portion5 as a l'ulcrnn'i, lint with the hook t; not yet quite in the clear. Thefinal seating may ii- :u-crnnplishcd now in] placing a crow-liar oroiher i'ilislruction helwcen the tie a id the hook to prevent movementof the hook toward the tin and giving the de ice an angir lar hammerhlow toward the tie applied at the roof oi {he V as indicat d hy thearrowlli in Fig. i.

tallies place in e tronsvcrre vertical plene and downwardly and inwardlyas stated, or in such a direction that the space between it nd thescat 9at the free end of the transverse member is reduced. Hence in the Finalsealing of the unchor from the position shown in Fig. 6 to that shown inFig. 2, the seals 8 and 9 must be spread further upert than wouldotherwise be the cuse, and the torsional strain in theverticol portion 5of the anchor is thereby correspondingly increased. As stated,the'rotetional movement of the jaw seat from the position shown in Fl 5to that shown in Fig. (5, produces e torsional strain in the portion ofrho longitudinal member between the jaw seat and the angle of the l-form. and that this torsional strainv is maintained by the engegen'icntof the lower shoulder 8 of the jaw seat with the under side of the railouse flange. it should be noted that this torsional strain is in such itdirection that it serves to hold the transverse member upwardly againstthe underside of the rail base.

ll :1 novel construction of the upper end and surface of hook 6, l. amable'to do away with the need of the crow be}? or other uuxiliery meansin installation. As illustrated in Figs. 7: and 8, the upper surfacehook (3 and the lip portion 6 is beveled upwardly away from the rail anddownwardly in the; direction away from the tie. The result is that withthe, hook resting inv the position shown in Fig. (l, the edge i? of thisupper surface near the tie is the only part in contact with the lowerfillet of the rail base on that side, and will rend to bite into thefillet when driven toward the tie. Because of this bite. or the frictiondeveloped at that point, hummer blows applied at the root ot' lhe V (lindimlcd. cause the 'el'lge G" to more outi'urzlly until the hool: 6 endlip 6 cleur the base edge.

Vfhcn the z'. gicz'ecwr is brought to position on ihc roll it can bemoved to ils final position abutting the tie by :ulditionul hum" merblows applied. at the root of the V us in-- (licuted. lo the event. ecrow bar or other obstruction is employed as described in ellecling themating: of (he anchor. it is of ci'nu'sc rcnuzvcd' before the anchor isbrought to in; final position against the tie.

The l'nearing face of the sent 9 is beveled preferably so that the rearedge, the edge further from lhe tie, will bite into the edge of the railbase like u planer tool or chisel in functional o 'ieration, The undersurface of lip (3 overhanging: seat 9 1S beveled so as to clear abovethe ruil base flange and not to interfere with, the perfect bite of edge9*.

As spccifigl for the device of my first prior patent cited t hut portronoil the upper port of longitudinal member 2 innocent to the root of theV may he made to lie clear above the upper surface of the lease flange.In other words, the vertical face oi seat 7 may he of greater depth thanthe thickness of the rail base flange edge. I take advantage of thispossible construction to introduce means whereby in functional operationthe bite or holding quality of seat 7 may be increased. Referring toFigs. 6 and 9, when the enticreepcr is first applied. to the rail, theseat 7 may be set lower than the final level shown in Figs. 1 and In theangle of seat 7 I form small blunt lceth T extend ing e shortdistenceVel'tllfilllly on part 5 and horizontally on the transverse member andhaving inclined edges. When thoulcvice is installed and is being broughtup to the tie the last hammer blows applied after the tic-abuttingportion coines in contact\\vith the tie, operate to lift these teethinto 'contact with the lower fillet of the base edge. The vertical planelever grip developed in functional operation by the tie reaction willthen cause the teeth to bite the rail.

in functional operation. the tie reaction is received by thetie-abutting member in horizontal direction, as indicated by the arrow10. Because of the initial friction in. installation of bearings 7 and8, this reaction of course tends to rotate the anchor counter clockwise,as viewed in Fig. 1, so that the bottom portion of the shoulder seat 7is pressed upwardly and the top portion 8 of seat 8 downwardly, so thatthcseseuts form the fulcrums or hearing points upon the rail buee flangeof. a lever grip operatii'e in a. vertical plane. As the reuction forceincrcuses sufficiently to produce any tendency to longitudinal movementoi the anchor along the rail, the force is transmitted to thelrunei'cmrt n'xeinbcr of the anchor through the connection 5. which isoutside t e seat 7, and (hereby establishing 2i lever grip on the milbase flange o zcral'ing in 2. horizontal plane with the seats: 9 and 'l'acting as the fulcrums or bearing points. i

To make the functional operation just described more positive and tostiffen the unticreeper in rcepect to the lever'grip operating in thevertical plane, the lower end of the lieubutting part l is braced by thepurl. 4 ugulnst the underside of member 2 adjacent dccribvd. The end ofthe part 4 is'prefcrubly so shaped minot to come into contact with therail base edge in normal 0 ration.

The :mticreeper is made prcfera ly from square rolled steel bar, and canbe manufactured without wuste. Fig. is drawn to illustrate a first stagein one way that may be followed in the manufacturing procefss. The. nextstage. changing to the lines of Fig. 1. will rcadllv be recognized.

It should be notcrl thut the mechanical features of my unticreepcrcomprise the s-Leut 7, as illustrated and alreadyspring clamp constru,-tion and the use of three distinctive seats or points for hearing onthe rail, whereby two combinations of two of the seats held in operativeposition by the third scatbecome the fulcrums of genuine lever grips. Bygenuine lever grip" is meant that type wherein the applied force reachesthe mechanism outside of the two fulcrums and not between them. Itshould further be noted that, the word ll-form in this description isused only to cover in an expressive way the general lines of aconstruction, connecting the three seats of hear ing, which will developand utilize the lever grips described.
